<h1>About <?rh-udv_start name="TechnologyName" ?>Unified Architecture<?rh-udv_end ?></h1>
<p>As the next generation of OPC technology, OPC UA (Unified Architecture) 
 is a major leap forward for secure, reliable and platform independent 
 interoperability. OPC UA is designed for the transport of data and information 
 from first-tier factory and process control devices through to the enterprise 
 information system.</p>
<p>The OPC UA specification, released in 2008, integrates all the functionality 
 from the existing OPC Classic specifications into a single service-oriented 
 architecture. It adds essential new features, such as platform independence, 
 scalability, high availability, embedded diagnostics, discovery and rendering 
 of complex information models, security, reliability, redundancy and more.</p>
<p>OPC UA provides a single set of services to expose the OPC data models, 
 such as Data Access, Alarms &amp; Conditions, Historical Access, and can 
 be implemented on non-Microsoft systems, including embedded devices.</p>
<p>OPC UA specifications are available to <?rh-udv_start name="CompanyName" ?>OPC Foundation<?rh-udv_end ?>
